This invention relates to a metal plate clamping and rotating device, belonging to the technical field of lifting, assembly, and transfer facilities. The device includes a crossbeam supporting a bidirectional threaded screw and a splined shaft, and a temporary storage platform located below the crossbeam. At least four threaded blocks, each forming a helical pair, are spaced apart on the screw. These threaded blocks and the crossbeam form a horizontal moving pair and support a drive wheel. The central hole of the drive wheel passes through the splined shaft and surrounds a lifting strap that engages with it. Hooks are installed at both ends of the lifting strap to hook onto the upper lifting rings of the lifting lugs. The middle of the lifting lugs is hinged to the end of the lifting beam, and a hook at the lower part of the lifting lugs hooks onto one end of a clamping plate. Elastic limiting posts extending downwards are distributed at intervals along the length of the lifting beam. This invention achieves reliable overall clamping of large-sized lead plates, significantly reducing defects such as lead plate deformation, scratches, and dents. It is adaptable to lead plates of different lengths, has a wide range of applications, and can meet the needs of different lead plate assembly angles, providing convenience and speed.

The utility model discloses an adjustable supporting arm structure for an electric tricycle, and relates to the technical field of tricycle supporting arms, the adjustable supporting arm structure comprises a fixing arm, the outer wall of the fixing arm is fixedly connected with a connecting structure, the inner wall of the connecting structure is slidably connected with a fixing bolt, and the outer wall of the fixing bolt is in threaded connection with a locking nut. A telescopic cavity is slidably connected to the outer wall of the fixed arm, a telescopic arm is slidably connected to the outer wall of the telescopic cavity, and an adjusting structure is fixedly connected to the outer wall of the telescopic arm. And long-distance adjustment depends on sliding adjustment of the telescopic arm and the telescopic cavity, and angle adjustment depends on cooperation of various structures, so that different vehicle types can be adapted, the assembly problem is effectively solved, the assembly speed is increased, the rework rate is reduced, and the production process is optimized.
